Abstract
Introduction: The study of the factors affecting the evaluation of furnace feed in the baking process is of great importance. If appropriate studies are not carried out on the evaluation of furnace feed, this can lead to problems such as increased production costs due to increased fuel consumption and electric energy consumption, reduced furnace production and increased furnace stops in the Clinker baking process. This research was conducted to evaluate the Gharb Cement Furnace feed of 4000 TPD kiln
Method: The research method was to first investigate mineralogy on mineral samples and then to study their microscopy in west cement factory. Grinding, baking ability, sampling of the factory mixing saloon, grain distribution, chemical composition, chemical composition fluctuations, chemical homogeneity and mineral composition in the evaluation of west cement feedstock feed.
Results: The results showed that the specimen number 885/6 has poor baking ability. According to the laser gradient distribution test, the sample was 885/10. The material has passed through 39.3 to 41 microns. That is, the sample of 885/10 is softer than the other two. The silica modulus of 885/10 is more suitable for baking than the other two. Also, the sample of 885/10, in terms of free silica content greater than 45 microns, has a more suitable taste for baking than the other two.The West Cement Furnace, during this time, accounted for about 26% of the total operating time for unusual and very hard baking conditions, with fuel consumption rising to about 6% per hour, as well as a 7% decrease in hourly production. Mineral studies on furnace feed samples show that carbonates greater than 125 microns are high and about 10 37/10 (maximum carbonates of more than 125 microns feedstock should be less than 8%), as well as the amount Free silica larger than 45 microns, this sample has been above the equilibrium (3.98), the maximum free silica greater than 45 microns should be 3%. This also weakens the baking ability of the specimen, and the presence of hard and coarse-grained quartz particles has led to an increase in the residual percentage of 90 microns to 18.1 percent, possibly due to the mixing of material from the separator with the milling material Raw materials.
